sqlite3: Enabling option to disable filesystem locking (POSIX advisory locks)
When sqlite database is expected to be stored on a NFS disk (e.g., a
home directory and ~/.ndnx/ndnsec-public-info.db is on NFS mount),
default POSIX advisory filesystem locks may not work properly, since
some NFS implementation do not support them. This commit allows
specification of ``--without-sqlite-locking`` to use alternative
"dotfile" sqlite locking mechanism.
